The Lady C occurrence is located at an elevation of approximately 730 metres on a northeast-facing slope, northwest of West Banon Creek and approximately 2.6 kilometres northeast of Mount Hall.

Regionally, the area is underlain by chert, siliceous argillite and siliciclastic rocks of the Mississippian to Pennsylvanian Fourth Lake Formation (Buttle Lake Group), calc-alkaline volcanic rocks of the Middle to Upper Devonian Nitinat Formation (Sicker Group) and volcaniclastic rocks of the Middle to Upper Devonian Mclaughlin Ridge Formation (Sicker Group). These rocks are intruded by granodiorite and quartz diorite of the Early to Middle Jurassic Island Plutonic Suite and gabbroic to dioritic rocks of the Triassic Mount Hall Gabbro. The sediments and pyroclastics are silicified and hornfelsed near the intrusive contact. Undivided sedimentary rocks of the Upper Cretaceous Nanaimo Group locally overlay the previous units.

Locally, an iron ore deposit (the Lady C) was located in the area in the early 1950s and is probably similar to the jasper-hosted Lady D deposit (MINFILE 092B 076), which occurs on strike several kilometres to the southeast. The Lady D is an exhalative-type iron ore deposit, consisting primarily of magnetite, occurring in the Devonian Nitinat Formation (Sicker Group).

Work History

The occurrence was first identified in the early 1950s.

During 1984 through 1986, BHP-Utah Mines completed programs of geochemical (rock, silt and soil) sampling, airborne and ground geophysical surveys, geological mapping and 16 diamond drill holes, totalling 6317 metres, on the JRM claims.

In 2001, Homegold Resources Ltd. conducted a program of geological mapping, prospecting and minor rock sampling on the area as the Holyoak 1-7 and 13-14 claims. A rock sample from the occurrence assayed 87.54 per cent iron oxide (Assessment Report 26629).
